Parts for the Dana 18 Transfer Case

The Jeep & IH Dana Spicer 18 is still one of the most respected transfer cases on the trail. Professional level rebuild work is possible for the conscientious shadetree rebuilder.

We offer nearly all parts at the component level, and our master rebuild kit, which includes the most thorough collection of parts offered anywhere.

The Master Kit
Our master rebuild kit has been assembled for our customer's rebuilds as well as our own. It is the most complete kit we've seen anywhere and features all the consumable and wear item components.

There are three kits available; one for each of the three major generations of the Model 18.

Rebuild Requirements
It is very common for our customers to do top-level rebuild work, using good methods and by following our included instruction guide.

We suggest the rebuilder have access to a set of snap ring pliers, and a small arbor press, in addition to standard shop tools. The full rebuild procedure is covered here.

Other Components
Essentially all parts for the Dana 18, including gears, shafts, etc. are available new and affordably so. Our parts ordering module is provided below. For anything not shown, contact us.

Dana 18 Billet Bottom Cover Pan
This extended capacity, billet bottom pan is the answer to a few Dana transfer case dilemmas. Its rigid flange replaces the thin, warped factory pans and virtually assures a drip-free seal.

In addition to this, its deeper pocket increases the fluid capacity of the Dana transfer case by about 16 oz., increasing the life of the components within. Dana 18 Bottom Pan

The pan is made of corrosion resistant 6061 aluminum and then anodized in clear zinc for further protection.

Included are the stainless socket head button cap screws, drain plug and sealing washer.

Kit D328-D, billet aluminum bottom cover pan, Dana transfer cases, deep version

Weight: 2.93
Price: $128.00

Includes the pan, drain plug and stainless fastening hardware. Gasket not included - RTV silicone will seal these machined surfaces best.

Dana 18 Gaskets & Seals Set
There's not a better gaskets and seals kit available. This one makes it possible to have a Dana 18 and a drip-free garage floor. The pan gasket itself (usually the most problematic) is cut from a rubber-cork compound.

Dana 18 PTO Port Cover
Sometimes utility and eye-candy can cross over. But, go ahead and get it muddy if you'd like. After seeing the difficulty of finding Dana 18 PTO covers, we added this one to our line-up. It's made from 3/16" thick aluminum (great for heat dissipation), media tumbled and anodized black. We follow up with a little engraving. Because of its rigidity, it will seal better than factory PTO cover.
